History and Experience

The YDSA Certifying Authority has been authorised by the Maritime and Coastguard Agency (MCA) since 1993. We have over 1,700 actively coded vessels, making us the largest MCA small craft Certifying Authority. The YDSA has delegated authority from the MCA to act on their behalf.

Not all members of the YDSA can act as Coding Surveyors. To survey a vessel for commercial compliance the surveyor concerned must have suitable experience and knowledge within the sector they wish to work. All Surveyors that wish to act through the YDSA as a Coding Surveyor must apply to the YDSA Certifying Authority, their application is assessed and if their application is passed, they will be included within a matrix of competencies reflecting the areas in which they can act and they are listed in the Find a Coding Surveyor directory.

Choice of Surveyor

With the YDSA Certifying Authority, you have a choice of Coding Surveyors. Our Coding Surveyors are selected from our membership of experienced Marine Surveyors, meaning they have proven experience in the industry. They are independent and you are free to nominate any YDSA Coding Surveyor from around the UK and overseas. You can change to another Coding Surveyor if your Nominated Coding Surveyor is unavailable.

Coding Surveyors are divided into two levels, according to their qualifications and experience:

  • Level 1: Coding vessels in all categories; carrying 16 or more persons; lifting/towing; carrying more than 1 tonne of cargo; and Pilot Boats.
  • Level 2: Coding vessels up to Category 2 not requiring a Stability Information Booklet.

All YDSA members hold Professional Indemnity (PI) insurance to cover both them you should the need arise.

Duty Surveyors

All paperwork is checked by senior CA surveyors who attend the office on a rota basis. They are highly experienced surveyors who know the Codes of Practice well and ensure your Nominated Coding Surveyor has undertaken a full inspection, checked the documentation and type of vessel against the relevant Code of Practice.

Keeping in Contact

We work closely with your Nominated Coding Surveyor to make the process as smooth as possible. If there are any queries regarding the Compliance Examination or any other paperwork, your Nominated Coding Surveyor is usually the first port of call.

We will contact you or your managing agent before your annual renewal is due, so you have time to arrange an inspection. If your Nominated Coding Surveyor is due to inspect your vessel, they will also be notified. This will include an Annual Declaration for you (or you and your Nominated Coding Surveyor) to sign and details of the Annual Renewal Fee.

Transferring Certifying Authority

If you are already registered with another Certifying Authority, you can easily transfer to the YDSA. If the person who manages the vessel and ownership remains the same there will be no extra cost. Your Nominated Coding Surveyor will need to perform an inspection to verify the current state of your boat, for which they may charge a fee.

Compliance Examination - Surveyor's Fees

The fees for the Compliance Examination are negotiated with and paid directly to the Coding Surveyor. The quoted fee will be on the basis that the vessel is presented for examination already compliant with the Code requirements. An additional charge may be made for a return visit or providing assistance with stability information.
